My initial question might be can the landlord charge rent on a property that is uninhabitable?
If it isn’t insured for flood damage than I suggest that questions might be asked about how likely it is that the claimants would be able to return to it anyway.
Annual income twenty pounds, annual expenditure nineteen nineteen and six, result happiness. Annual income twenty pounds, annual expenditure twenty pounds ought and six, result misery. The blossom is blighted, the leaf is withered, the god of day goes down upon the dreary scene, and—and in short you are for ever floored.
Wilkins Micawber, Ch12 David Copperfield
